Description

A fully automatic tree whitening machine

technical field

The utility model relates to the technical field of tree whitening machines, in particular to a fully automatic tree whitening machine.

Background technique

Tree trunk whitening refers to a green and environmentally friendly control method that uses different formulas to make whitening agents and smears them on the base of tree trunks according to the purpose of prevention and control. , South painted white 2 times. According to the latest data from Hebei Province, the province's forest coverage rate has increased from 31% at the beginning of the "13th Five-Year Plan" to 35%, and the forest stock volume has increased from 144 million cubic meters to 175 million cubic meters. The number of whitened trees will increase from 46,000 in 2018 to nearly 100,000 in 2021. It can be seen that the traditional whitening method needs to be improved urgently, and the current market whitening machine cannot meet the needs of tree whitening. The development of new whitening machines is imminent. Traditional whitening The method is to dip the whitening agent with a hand-held brush or spray it with a sprayer. There are problems such as high work intensity, low work efficiency, and uneven quality, and it is easy to come into contact with harmful chemicals and endanger the health of workers. At present, there are many types of whitening machines on the market, all of which are extended-type whitening machines, and the whitening work is still mainly done manually.

1. Bottleneck factors of whitening trees in my country

According to the analysis of big data, the distribution of trees in my country is extremely wide, and the species are diverse. The diameters of trees vary due to different species and planting years. Even the same tree in the same place presents different shapes from top to bottom. Generally speaking, the trees on both sides of the urban roads are relatively straight and thick, while the trees in the green belt are thin and inclined. Theoretically speaking, the spraying device needs to actively adapt to the irregular changes in the diameter of the tree. The current technology can realize it, but the cost is high, the operation is complicated, and the workers need long-term training before using it, which greatly restricts the tree whitening machine. The scope of application and economical practicability; the size of the whitening machine also restricts the development of automatic tree whitening in my country. The large machine is heavy and heavy, although it has more liquid, but the battery life is poor, and the small machine has less liquid. , strong battery life, but it takes a long time to fill the liquid multiple times. At present, the above-mentioned problems basically exist in the tree whitening machines in my country. At present, the tree whitening is still mainly manual, and the mechanization is greatly restricted.

2. Analysis of the status quo of tree whitening technology in my country

1) The scope of application is small.

At present, non-adjustable whitening machines have a wide range of applications, and are mainly used to spray trees that grow more regularly on both sides of the road. However, in practical applications, it is often encountered that the trunk has a large bend, many branches, and a large difference in diameter, etc., which are beyond the size adjustment range of the non-adjustable whitening machine. In addition, the diameters of the mechanical arms and open cylindrical sleeves of most spraying devices cannot be adjusted. In actual spraying, only the pressure of liquid spraying can be controlled to adapt to trees of different diameters, resulting in more consumption of spraying liquid and affecting spraying efficiency and effect. . And shrub trees hardly have applicable whitening machines.

2) There are defects in the whitening machine.

Some urban greening trees will be fixed and protected by fences, but the width and height of the fences are not uniform. Currently, the whitening equipment in the market cannot make corresponding adjustments according to the size of the fences. You can only choose to spray trees outside the fences. There are also some trees planted on the sidewalk or the isolation belt in the middle of the road, which is inconvenient to work due to walking obstacles. However, in the design, these factors are often not considered sufficiently, resulting in that the machine cannot be adjusted in time according to different environmental conditions, and it is difficult to implement spraying and affect the spraying effect.

3) The machine manufacturing process is complicated and the economic benefit is low.

Although the non-adjustable whitening machine and the adjustable whitening machine have high spraying efficiency and good spraying effect, the manufacturing process is complicated, and general enterprises cannot manufacture on a large scale, the spraying cost is high, and it is easy to be restricted by terrain. At present, hand-held electric sprayers are widely used in the market, and their cost is far lower than that of non-adjustable whitening machines and adjustable whitening machines. They can adapt to complex terrain and have high flexibility. There is less liquid in reserve, so it is not suitable for long-term spraying; the spraying pipe is easy to block, and it takes multiple sprays to completely spray a tree, resulting in a lot of liquid waste.

Aiming at the problems in the related technologies, no effective solution has been proposed yet.
